Huwei Ascend Cynogenmod - How to flash back or fix problems

[nonzero]

I bought this phone off of craigslist since mine got ran over. The Rom seems ok but it has a few things that are driving me crazy.

1. MMS almost never works (ran fix permissions, waiting to see if that fixed anything with mms)

2. No option for Swype, anywhere, tried downloading and installing from market. It doesn't work.

3. On the dial pad, it no longer allows me to spell out the name and list and drop names as punch in (ie I press 7 3 and a list drops showing Peter and Peri). I am forced to go to contacts and scroll through list (Very annoying when you have a ton of contacts and need to call Will or Vicky!)

I don't know if its an issue with the Rom its self or if it was something the previous owner did. I've tried looking for answers to these problems, but very few people have this phone.

Can I fix these problems. The rom is Cyanogenmod 7.2. The rom seems to run smoother, uses less memory than the stock one that was on my old phone, and has the newer 2.3.5 Android OS. I'd rather fix these problems, but if I can't, can I go back to stock? Any help to solving these issues would be greatly appreciated.
